What was found
DAMAGE AREA 1, AFFECTING THE CENTER FUSELAGE I LOWER RIGHT SKIN PANEL (P/N 170-92574-005) JUST FORWARD OF FR23 AND ABOVE STGR-13R COULD NOT BE REPAIRED THROUGH A MINOR REPAIR IN ACCORDANCE WITH SRM 53-00-00/REPAIR 03P BECAUSE THE AFFECTED HOLE SIZE EXCEEDED THE ALLOWABLE LIMITS. EAMS REQUESTED AND RECEIVED A REPAIR FOR THE AFFECTED HOLE IN THE FORM OF ETD2020-170-002280, WHICH PROVIDES TWO OPTIONS TO ACCOMPLISH A PERMANENT REPAIR. OPTION 1 IS TO REAM THE HOLE TO REMOVE THE DAMAGE AND INSTALL REPAIR BUSHING PER SRM PART II 51-10-07, CASE 1. OPTION 2 IS TO CUT OUT THE DAMAGE AND INSTALL A REPAIR DOUBLER. THIS EO IS BEING ISSUED TO PROVIDE INSTRUCTIONS TO ACCOMPLISH OPTION 1, WHICH IS THE PERMANENT REPAIR OF DAMAGE AROUND A FASTENER HOLE BY REAMING THE HOLE AND INSTALLING A REPAIR BUSHING. BECAUSE THE CENTER FUSELAGE I LOWER RIGHT SKIN IS A PSE AND THE EO IS RESTORING STRENGTH, ACCOMPLISHMENT OF THIS EO HAS BEEN CLASSIFIED AS A MAJOR REPAIR. OPTION 1 DOES NOT REQUIRE SUPPLEMENTAL FOLLOW-ON INSPECTIONS PER ETD2020-170-002280. EO E175-53MR-486 IS BEING ACCOMPLISHED BY WO 2821166
